28 Claims. (Cl. lOl-4'?) This invention relates to a printing machine, and especially to a sheet feeding and listing mechanism therefor, toV enable lists to be made from a series of printing devices. f

The general object of the present invention is to provide a printing machine with a listing mechanism or sheet feeding device, particularly arranged to permit lists to be made from worksheets of a comparatively large size.

A further object is to provide a printing machine of the type. having an overhanging platen arm supported on a frame table, with a work sheet feeding device particularly arranged to permit lists and the like to be made on -work sheets of such size that ordinarily listing thereon would be prevented by interference with the overhanging platen arm.

A more specic object of the present invention is to provide a series printing machine, such as an addressing machine, with a listing mechanism to automatically feed a worksheet to enable impressions to be made thereon in list formations, and to so handle the impressed area of the sheet as to permit comparatively large worksheets to be retained in close proximity to the printing mechanism without interfering with thefeeding of the sheet and Without damaging the sheet by folds, creases or the like.

I prefer to accomplish the object of this invention by providing a sheet feeding orlistingl mechanism to automatically feed a sheet to a series printing machine and which mechanismwill automaticaly roll or wind up the printed sheet consequent upon the operation of the printing mechanism.

Other objects of the present invention will be,- come more apparent from the following description, reference being had to a preferred form of the invention, illustrated in the accompanying drawings. The novel features of the invention will be set forth in the claims.

In the drawings, Fig. 1 is a plan View of a printing machine. and listing device provided with my improved sheet feed; Fig. 2 is a longitudinal section indicated by the line 2 2 on Fig. 1; Fig.. 3 is a fragmentary side elevation of the machine and listing mechanism looking at the right-hand side of the mechanism as viewed in Fig. l; Fig. 4 is a fragmentary side elevation, similar to Fig. 3, but illustrating certain parts in different operating positions; Fig. 5 is a fragmentary sectional view on a greatly enlarged scale, the plane of the sections being indicated by the line 5-5 on Fig. l; Fig. 6 is a transverse section, as indicated bythe line 6-5 on Figs. l and 5, the scale by the line VI--Ill on Fig. 9;

of the section being the same as that of Fig. 5; Fig. '7 is a sectional detail, the plane of the section being indicated by the line 'I-l on Fig. 6; Fig. 8 is a sectional detail, on the same scale as Figs.V 5, Gand 7, the plane of the section being indicated by the line 8-.8 on Fig. l; Fig'. 9 is a perspective view illustrating the sheet feeding table and roller mechanism, removed from the machine; Fig. l is asectional detail, as indicated Fig.V 11 is a. substantially horizontal section,-as indicated by the line II-II on Fig. 10.

In the drawings, 1 have illustrated my improved printing mechanism in connection with anv addressing machine of the type 'shown and described in my prior application for Letters Patent, Serial No. 62,416, filed February th, 1936, and assigned to my assignee, Addressograph Company. As illustrated in Figs. 1 and 2, such a machine comprises -a main frame I9, provided with the horizontal guideway Il, along which printing -devices such as address plates D are progressed, oney after another, from the bottom of a stack indicated at I2 to an anvil I3 and thence to a second stack I8. Y

. A suitable conveyor, such as a pair of reciprocating feed bars I4, is provided to progress the printing `devices from one stack to another. The feed bars are reciprocated by an eccentric l5, which is connected by links and levers I6, with the feed bars. The eccentric I5 is secured to a shaft A22 journalled in the frame. Ill and rotated by a motor M.

When the feed bars I4 move to the right, from the position shown in Fig. l, suitable abutments I9 thereon engage the bottommost printing device in the stack I2 and shove it towards the anvil I3, the same operation causing all devices in the guideway II to be moved, by suitable springpressed `pawls I1, carried by the feed bars. In this manner the printing devices come, one after another, to rest in printingI position, namely, on the anvil I3. Y Y

Theplaten illustratedis of the roller type and is supported by a pair of spaced frame brackets 26. These brackets or arms extend from frame I0 upwardly, forming the magazine l2 at the rear of the .guideway II, and then extend forwardly above and parallel with the guideway. The brackets are spaced apart a distance substantially equal to the length of the printing devices, and are each provided with an inwardly facing guide rail 2|, along which the platen meehanism isreciprocated.

A more complete description of the platen and its operating mechanism is given in my copending application for Letters Patent, Serial No. 63,575, led February 12, 1936, and assigned to my assignee, Addressograph Company. Briefly, the platen mechanism comprises a carriage 25, which is slidably mounted on the guideways 2l carried by the platen arms 23 in such a manner that the carriage is supported between such arms.

Mounted in the carriage 25 are a pair of shafts 3U and 3l, which support .a toggle mechanism comprising two pairs of links (one pair of which is shown at 32, 33 in Fig. 2). Each link 32 is pivotally connected to the shaft 33 and to its respective link 33. Each link 33 is in turn pivotally connected, as illustrated in Fig. 2 to a platen shaft 34, which rotatably supports the platen 35. A third pair of links 3S guides the movement of the platen. Each of these links is pivotally connected between the platen shaft-34 and the shaft 3l, heretofore mentioned.

Any means, such as a suitable spring (not shown) may serve to maintain the platen normally in the position shown in Fig. 2. However, when the platen approaches the right-hand end of the brackets 26 (Fig. 2) a roller 36, carried by the pivotal connection between the links 32 and 33, engages an abutment 3l', formed on a bracket 23, preventing subsequent movement of the pivot, whereupon continued forward movement of the carriage causes the links 32 and 33 to be aligned, both links extending downwardly from the shaft 30, whereby the platen is moved into engagement with a worksheet W superimposed above the printing device, carried by the anvil i3.

Following the engagement of the sheet by the platen, the platen carriage is drawn to the rear (to the left in Fig. 2), causing the platen 35 to be rolled across the printing device supported on the anvil E3. A suitable inked ribbon R disposed between such device and the worksheet causes an impression to follow. When the platen approaches the rear or left-hand limit of its stroke (Fig. 1) an abutment, similar to that shown at 37, may be employed to engage the roller 36, whereupon continued rearward movement of the carriage will cause the links to return to the position illustrated in Fig. 2.

The platen carriage may be `reciprocated by any suitable means. I have shown, however, in Fig. 2, an eccentric 40, which is connected to a rock arm tl, by a suitable connecting rod 42. The rock arm il is rigidly secured at one end to a shaft 43, journalled in the frame, and its other end is connected by a link d with the platen carriage. l

It will thus be seen from the foregoing description that consequent upon the rotation of the shaft 22, to which the eccentrics l5 and 40 are secured, the printing machine will operate to make successive impressions from the successive printing devices on a worksheet W.

The present invention comprises a listing device for handling the worksheet W, so that lists, such as a list of names, addresses or the like, may be impressed on the paper, one below the other, in columnar formation, on worksheets of lengths considerably greater than the distance from the anvil i3 to the vertical extending portions 23 of the platen-supporting brackets.

As shown in Figs. l and 2, the listing mechanism, which forms the subject of this application, comprises, in general, a work table, or guide, 5R, arranged to be secured in position on the top of the frame lli, and provided with a takeup roller 66 or other means by which the work sheet is coiled or rolled, following each impression made thereon, as will be hereinafter more fully described. The table 5G extends, as indicated, from a point located forwardly of the anvil I3, (the right in Fig. 2), to a point adjacent the columnar supports 23 of the brackets 20.

The worksheet is initially positioned with its foremost edge between a pair of feed rollers 'l0 and 1I, located intermediate the anvil and the roller 6E at one side of the guideway H. These feed rolls serve to progress the sheet W from the anvil to the roller 60. It will be noted from Figs. 9 and l0, that the work-supporting plate 5l) nearly encircles the roller Si), being formed at its rearmost edge with the tubular portion 5l extending above the plane of the plate and arranged to enclose the cylinder or roller 60. The internal diameter of the tubular portion 5l is somewhat greater than the external diameter of the roller, so that the worksheet may be wrapped around the roller a number of times without binding between the roller and the tube.

The operation of my improved paper feed or lister mechanism is as follows:

The operator positions the worksheet on the table 50 so that its forward edge is gripped by the feed rollers l0 and 7|, whereupon the printing mechanism, comprising the plate feed and platen operating devices, heretofore described, is set in operation, causing an impression to be made on the worksheet from the printing device resting on the anvil I3.

Following the making of such impression, the platen is raised clear of the work, the printing devices are advanced to position the next succeeding device on the anvil; the feed rollers 1D and 'H- are operated to cause the worksheet to advance to position a fresh portion thereof above the anvil. A second impression is then made, the platen returned and the paper advanced and so on.

As the worksheet W is advanced by the feed rolls 10 and 1l, it is guided into the bite between the small rollers 6I and the roller 6D, the latter, as will hereinafter be described, being rotated in timed relationship with the movement of the feed rolls, so that the impressed sheet is periodically advanced, and wrapped about the roller 60.

When the last impression desired on the sheet has been made, the operator stops the operation of the printing mechanism, separates the rolls 'l0 and 1|, and at the same time disconnects the roll 60 from its driving mechanism, whereupon the sheet may be readily drawn forwardly from the roll 6U and a new sheet inserted between the feed rolls, whereupon the operation may again be repeated.

After a sheet has been withdrawn, a second column may be impressed thereon by moving the sheet either to the right or the left, a distance equivalent to the desired spacing of the columns, whereupon the sheet may again be progressed through the mechanism and a second column of addresses or other subject matter impressed thereon.

The feed rolls and the take-up roll are driven from the shaft 43 to which the platen-operating arm M is secured, as heretofore described. In Fig. 1, I have shown an arm 80, as drivingly connected to the shaft 43, so that consequent upon the rotation of the eccentric 40, the arm will be oscillated. Removably pivoted to the arm by a suitable pin 8l is a link 82, also pivotally connected as at 83 with a lever 84, pivote'd as at 85 to a bracket 86. The lever 84 is, as shown in Fig.

5 by the bracket 86.

5, connected by a link 88 with one leg 81 of a U shaped lever 99, such leg being pivoted as at 89, to the bracket 86. The other leg 9| of the U shaped lever is provided with a slideway 93, which slidably supports a link 92. This link 92 has a pivot pin 99 which extends through a suitable slot in leg 9| of the lever 99 and is secured to a block 98 which is adjustably secured to the lever 95 by an adjusting screw |09.

By changing the relation of the pivot pin 90 to the pivot 89 of the lever 99 the stroke of this lever mechanism may be adjusted as desired. The link 92 is also pivotally connected, as at 94, with a crank 95, mounted on a shaft 96, carried Mounted on the rock shaft and drivingly connected to the crank 95, is a segmental gear 91, which, as shown in Figs. 3 and 4, meshes with a pinion |00, rigidly secured to the driven member of a suitable uni-directional clutch carried by a shaft |02 journalled in the frame bracket 86. The driving member |03 of this clutch is secured to the shaft |02, so that consequent upon the oscillationof the segmental I gear 91, the shaft |02 Will be periodically turned in one direction.

The feed roller 1 0 is drivingly secured to the left-hand end (Fig. 6) of the shaft |02. Immediately below the shaft |02 I provide a second shaft |04, which is journalled to the frame bracket 86 and drivingly carries the feed roller 1| which lies beneath the worksheet W, and coacts with the roller 10 to grip and feed the sheet. A pinion E95, drivingly carried by the shaft |04, meshes with a gear |06 drivingly secured to the shaft |92. Hence, the rollers 10 and 1| will be rotated in unison.

The rotative movement of the shaft 02, as heretofore described, results from the movement of the shaft 43 which is operated by the platenoperating eccentric 40. It therefore follows that the paper feed rollers 10 and 1| will be periodically driven in timed relationship to the operation of the address printing mechanism heretofore described.

As heretofore mentioned, to insert a sheet between the feed rollers 10 and 1|, I prefer to separate the rollers. For this purpose I undercut the shaft |02 as at 21, for considerable length, reducing the diameter of the shaft to such an extent that the shaft becomes somewhat exible. The left-hand end of the shaft is mounted in a bearing im, which is mounted for vertical movement ina slideway |08 of the bracket 86. A leaf spring |09 bears against the top of the bearing member |01, and acts to maintain the roller 10 normally in engagement with the roller 1|.

To raise the roller 10 clear of the roller 1| I provide a rock shaft H0, the left-hand end of which, as shown in Fig. 6, has a cam surface arranged to engage a face ||2 of the bearing member |01, and so arranged that consequent upon the swinging of a shaft ||0, by a manually operable lever ||3, secured thereto, the bearing member |01 will be raised upwardly, separating the rollers 16 and 1|.

To enable suitable positioning of the sheet after it has been gripped between the rollers, consequent upon the release of the operating lever i3, I prefer to provide the right-hand end of the shaft |02 with a knurled knob ||4, which may be grasped by the operator to rotate the shaft independent of its operating mechanism.

The uni-directional clutch |0|, |03 being Aof the roller type, having its driven member loose on the shaft, this movement of the shaft |02 is readily accomplished without affecting the operating mechanism and without disturbing the timed relationship between the shaft and its driving mechanism.

The take-up roller 60, upon which the sheets are rolled during the printing action, permitting the printing mechanism to utilize a comparatively long sheet without interference of the sheet by the various members of the printing mechanism, is periodically driven and in timed relationship with the feed rolls 10 and 1|. As illustrated in Figs. 1, and 8, the roller 69 is provided with a suitable friction surface 62, such asrubber, similar to that used on a platen and is secured in the usual manner to a shaft 63, journalled in bearings 64 secured to the feed table 50 by screws 54. These bearings 64, as shown in Fig. 8, serve to maintain the shape of the tubular portion 5| of the feed table, the latter being secured thereto by screws 53.

The take-up roll shaft 63 is driven from the gear |06 of the feed roll shaft |02. As illustrated in Fig. 8, the shaft 63 extends some distance beyond the end of the right-hand bearing member 64, and has rigidlysecured to it a clutch member 65, carrying a pin 66, upon which a series of discs 61, rotatably encircling a sleeve 68, are mounted for axial movement relative to the shaft and sleeve. These discs are interleaved with discs of a second set of discs 69, which are keyed to the sleeve as indicated at |20, Fig. 8. A second sleeve |21, slidably mounted on the first sleeve, is normally engaged by a compression spring |22, and maintained in engagement with the endmost disc retaining the discs 61 and 69 in frictional contact 9 with each other, whereby a driving connection is normally maintained between the shaft 53,'upon which the sleeve is rotatably journalled, and an aligned stub shaft |24 to which the sleeve is pinned, as indicated at |25.

The stub-shaft |24 is journalled in the bracket 86 and is provided with a driving gear |26, constantly meshing with an idler gear |21 mounted on a stud |28 carried by the bracket 36 in the usual manner. The idler gear meshes with the gear |06 of the feed roll shaft |02, thereby driving the roll 60 periodically in timed relationship with the feed roll 10.

Inasmuch as I contemplate the wrapping of the worksheet several times about the periphery of the roll, an adjustment is provided, in which the driving connection between the discs may be regulated, soas to permit a certain amount of slippage to prevent the winding of the worksheet from interfering with the progression thereof by the feed rolls and 1i. As shown, this .adjustment comprises a nut |29, threadingly carried by the sleeve 68 and arranged to increase or decrease the pressure of the compression spring |22 as desired, to the end that the rotation of the roller serves only to wind the sheet and retain it taut.

The worksheet W is maintained in contact with the take-up roll 60 by suitable rollersvGl, heretofore mentioned. These rollers 'are best illustrated in Figs. 9 and 10. As there shown, I provide three roller units, each of which comprises four rollers 6|, carried in pairs, one pair arranged to engage the take-up roll 60 from one side, and the other pair from a substantially diametrically opposite side.

Each pair of rollers 6| is mounted on a rod |3 These rods are individually mounted for movement toward the axis of the roll v50, in respective slots formed in ears |32, punched outwardly from the tubular portion 5| of the feed plate 5|).v As

shown in Fig. 9, the rollers 6| of each pair are spaced apartfrom each other on its supporting rod, and the rod therebetween is engaged by one end of a spring |33, the other end of which, as at |34, engages the rod of the diametrically opposite roller. The spring |33 maintains the rollers in contact with the roll 60, or the sheet wrapped therearound, the rollers 6| extending, as illustrated in Fig. 9, through the slots in the tubular housing resulting from the forming of the ears |32.

When it is desired to withdraw a worksheet from the machine, the rollers 16 and 1| are separated, and the roll 60 is disconnected from its driving mechanism. The rollers 16 and 1| are separated for this purpose by swinging of the lever ||3 clockwise (Fig. 5). rFhis movement of the lever ||3 also disconnect-s the driving connection between the take-up roll shaft 63 and its driving shaft |24, whereupon the roll is free to be rotated, thus permitting the unrestricted withdrawal of the sheet from the tube 5|.

As indicated in Figs. 5 and 6, the hub of the lever ||3 is provided with a cam surface |56, arranged to engage one end of a lever Ml, pivot-ed intermediate its ends to the bracket 36, as shown in Fig. 1, at |42. The other end of this lever is provided with a yoke formation embracing the sleeve |2|. The arms M3 of this yoke are provided with suitable pins |46 which engage the Walls of an annular recess E55 in the sleeve |2|, so that consequent upon the swinging of the lever ||3 to separate the feed rolls 16 and 1|, the sleeve |2| will be moved toward the right (Fig. 8) against the action of the spring |22, relieving the pressure between the discs 61 and 69.

The feed table or plate 56 is secured to the bracket 86 in any well-known manner, such as, for instance, by screws extending through openings 55 in the plate and engaging the brackets. Hence, the feed table and bracket may be removably secured as a unit to the printing machine. As shown, the feed table and bracket 86 are provided on their undersurfaces with a plurality of forked attaching clips |50, arranged to engage the heads of suitable studs |5| which are mounted for vertical movement in the frame I6 of the printing mechanism and normally maintained in their lowermost positions by compression springs |52. Thus, the lister, comprising the feed table 5D and its operating mechanism, may be readily slid into position on the printing machine. The lister Lmit is secured in position `on the printing machine by a rod |56, the lower end of which is provided with suitable threads |51 arranged to engage a frame boss |6a of the printing machine. If desired, a locating pin, such as indicated at |58, in Fig. 5, may be secured to either the printing machine frame I6, or the lister bracket 86, and engage suitable location openings in the other member.

As heretofore mentioned, the printing operation is carried out through the medium of a ribbon R, which lies Vbetween the printing device D and the worksheet W. To protect the Worksheet from the printing device, I prefer to cover as much as possibleof the ribbon R with a comparatively thin metal sheet or guard |69 which has a cut-out portion i6! of sufficient size to permit the exposure of only that portion of the ribbon lying immediately above the printing characters of the printing device.

The guard |66, as shown in Figs. 9 and 10, is considerably thinner than the feed table 5|), and is secured thereto by suitable pins |62 arranged to engage suitable recesses or notches |63 formed in an undercut portion of the plate 50. The plate 50 is provided with an opening |65, through which the feed rollers 10 and 1| extend.

To align the sheet on the guide table 50, I prefer to provide the lister with a pair of guides |66. These guides each comprise an angular shaped member having one leg |61 in engagement with the surface of the feed table 56 and an upstanding leg |68 to guide the edge of the sheet for movement in a direction parallel with the printing device Vguideway '.Ihe guides |66 may be rigidly secured to the ends of rods |69 which are slidably mounted in brackets |16 or 1|. These brackets are carried by the feed table 56 and the bracket 86 respectively. Set screws |12 are mounted in the usual manner in the brackets |10 and |1! to retain the guides |66 in an adjusted position to accommodate sheets of various widths, as well as to enable multi-columnar lists to be readily made.

.said mechanism comprising a power operated feeding means arranged and adapted to feed a sheet a predetermined distance at a predetermined lineal speed following each impression, a roller, means to guide the impressed sheet into contact with said roller, means to maintain said impressed sheet in contact with said roller, and means frictionally connecting the roller with a moving part of the addressing machine to rotate the roller to move its periphery at a greater rate of speed than the lineal speed of said sheet, due to the action of said feeding means, and means to permit the sheet to be unwound from said roller.

23. A sheet-feeding mechanism comprising a planular sheet supporting table having the forward end thereof gradually merging into a tube formation, a pair of separable feed rolls mounted on said table and arranged and adapted to grip a sheet, means to periodically rotate said rolls to feed the gripped sheet forward a predetermined distance, a roller axially mounted in said tube and having its periphery spaced apart from the internal Walls of said tube, rolls supported by said tube and projecting through openings in the tube, resilient means to urge said last-named rolls into contact with the roller, means to intermittently rotate said roller consequent upon the operation of said feeding means to cause the periphery of said roller to travel a greater distance than the distance the feed rolls advance the sheet, friction driving means interposed between the last-named means and said roller whereby that portion of the sheet between the feed rolls and the roller is maintained in tension, and means to separate said feed rolls and disconnect the driving means from said roller to enable the sheet to be manually unwound from said tube and drawn rearwardly across said table.

24. In a listing mechanism, the combination of means for making successive impressions on an individual sheet, a slotted tubular member containing a wind-,up mechanism, means for feeding the impressed sheet into the tubular member, and means'for attaching the sheet to the wind-up mechanism by the mere act of feeding it into the tubular member.

25. In a listing mechanism, the combination of means for making successive impressions on a detached sheet, means to automatically grip the sheet and wind it up following the impressions, and a slotted tube substantially surrounding the wound up sheet.

26. In a listing mechanism, the combination of means for making successive impressions on a detached sheet, means to feed the sheet a denite amount for each impression, independent wind up mechanism adapted to grip the sheet, and mechanism enabling it to maintain the sheet wound up at a rate caused by the feeding mechanism.

27. 'I'he combination of means for making successive impressions on a detached sheet, a roller and gripping means adapted to automatically receive the end portion of the impressed sheet, and a friction drive for the roller whereby the sheet is Wound up about the roller.

28. A listing mechanism, the combination of means for making successive impressions on a work sheet, a substantially tubular member having a slot into which the sheet may pass, a pair of feed rollers to engage the sheet and feed it a definite distance for each impression, into the tubular member, a winding roller within the tubular member, a gripping roller extending through an opening in the tubular member into engagement with the winding roller, and a friction drive for the winding roller.
